TECHNICAL FIELD

[0001] The present invention relates to a remote-control system of an electric apparatus in which a driving control operation can performed by a predetermined operation unit when the user is at home, performing a remote-control the electric apparatus from an external communication device when the user is out, a remote control method of an electric apparatus, and a base station performing a remote control of an electric apparatus.

BACKGROUND ART

[0002] In electric apparatuses, some of them can be on-off operated from a remote place through push button operations on a telephone when the user is out.

[0003] For example, in an air conditioning apparatus serving as such an apparatus, the user makes a phone call on a push-button-type telephone when he or she is out, so as to confirm the operation state of the apparatus and switch the operation/stop states through push-button operations.

[0004] More specifically, as shown in FIG. 5, a tele-controller device 2 (hereinafter, referred to as “tele-con”) is connected to an air conditioning apparatus 1, and this tele-con 2 is connected to a public telephone line network 3. Then, a dial-up connection is made to the tele-con 2 from a push-button-type telephone 4 located at a remote place, and after the personal identification and the like have been made by inputting a pass number, a predetermined signal is transmitted to the tele-con 2 by push-button operations through the push-button-type telephone 4 so that the on-off control is carried out on the air conditioning apparatus 1. Here, a controller 5, which is used by the user at home to control the air conditioning apparatus 1 in the vicinity thereof, is connected to the air conditioning apparatus 1; thus, modes are switched between a home-use mode and a tele-control mode (hereinafter, referred to as “tele-con mode”) by using this controller 5.

[0005] Therefore, in the case of the home-use mode, the user operates the controller 5 at home so as to control the air conditioning apparatus 1, while, in the case when the user is out, after the mode has been switched to the tele-con mode by the controller 5, the remote control is carried out on the air conditioning apparatus 1 by using a push-button-type telephone 4 located at a remote place through the public telephone line network 3 and the tele-con 2. Here, the functions of the remote control are basically determined by a software program that is built in the tele-con 2.

[0006] However, in the above described conventional methods, when there is no push-button-type telephone 4 where the user goes out, no operation is available. However, in recent years, along with the developments of the Internet, new communication media or communication apparatuses such as cellular phones and personal computers with communication functions have been generally used, and there have been ever-increasing demands for methods of remote-control operations of electric apparatuses suitable for these various platforms.

[0007] Moreover, in some cases, there is a demand for adding an operation menu for remote-controlling that has not been prepared at the time of the shipment of each electric apparatus. For example, in the case of the air conditioning apparatus 1 serving as the electric apparatus, there are some demands for adding automatic setting functions for rainy season and dry season in winter in humidity adjustments and for adding new automatic temperature adjustments and the like to the operation menu so as to adjust to any un-precedential weather due to the current abnormal weather. In such cases, in the above-mentioned prior-art methods in which all the remote control functions are defined by software programs inside the tele-con 2, even when the maker of an electric apparatus attempts to add and update an operation menu, functions and the like, the maker needs to recall all the tele-cons 2 or go to the installation sites of the tele-cons 2 so as to update the inner software program. Therefore, actually, it has been difficult to add new functions and update the operation menu in remote control systems.

BEST MODE FOR CARRYING OUT THE INVENTION

[0034] <Configuration>

[0035]FIG. 1 is a block diagram that schematically shows a remote control system of an electric apparatus 11 according to one embodiment of the present invention, and FIG. 2 is a block diagram that also shows its structure in detail.

[0036] As shown in FIG. 1, in this remote control system, an electric apparatus 11 and a base station 12 are connected to each other through a packet network (communication network) 25, and when the user is at home, the user directly controls the electric apparatus 11, while, when the user is out, the electric apparatus 11 is remote-controlled by utilizing communication devices forming various platforms such as a push-button-type telephone 13 and a personal computer 14 that is allowed to communicate through the Internet or a cellular phone 15 (hereinafter, referred to as “Internet communication devices 14, 15).

[0037] A typical example of the electric apparatus 11 is an air conditioning apparatus (hereinafter, referred to as “air controller”), which drive-controls a driving system 11 a that is provided with a compressor, a blower fan and the like, by using a control system 11 b. In the case of the operation when the user is at home, the user operates a predetermined remote controller (operation unit) 11 c, etc., so that an operation signal is transmitted to the control system 11 b, and on the basis of this operation signal, the control system 11 b controls the driving system 11 a. Moreover, the electric apparatus 11 is provided with a communication circuit 11 d that is connected to the packet network 25 such as general public telephone lines, and is allowed to communicate with a base station 12 through the communication circuit 11 d.

[0038] More specifically, the driving system 11 a of the electric apparatus 11 is provided with actuators for various driving devices, such as the compressor and blower, and various sensors that detect the temperature, humidity and the like in the vicinity of the various driving devices. The various actuators are operated in accordance with operation signals sent from the control system 11 b. Moreover, the various sensors carry out various detections every predetermined time on the basis of the operation signals from the control system 11 b so that the results of the detections are transmitted to the control system 11 b as detection signals.

[0039] The control system 11 b of the electric apparatus 11 is provided with a ROM, a RAM, a CPU, not shown, and a storing device, and the CPU is operated in accordance with a processing sequence described in a software program (hereinafter, referred to as “device program”) preliminarily stored in the storing device.

[0040] Moreover, the device program is defined so that, when detection signals from the various sensors of the driving system 11 a are received, various driving control states are stored in the storing device every predetermined time in an updating manner as the detection result information in the form of data rows that have been subjected to various encoding processes, and, when a request signal for the state confirmation is given from the base station 12 through the packet network 25, the corresponding detection result information, stored in the storing device, is transmitted to the base station 12.

[0041] The base station 12 is provided with a Web server (second input unit) 21 connected to the Internet (first communication path) 20, a telephone automatic answering system (first input unit) 23 connected to a public line network (second communication path) 22, a user managing server 24 which manages users of the respective electric apparatuses 11, a tele-control server (remote control unit: hereinafter, referred to simply as “tele-con server”) 26 that carries out remote control operations by individually making connections to the respective electric apparatuses 11 through the predetermined packet network 25.

[0042] The Web server 21 uses a computing system that is provided with a predetermined storing device 27 a (FIG. 1) such as a CPU, a RAM and a hard disk drive, and is provided with a Web page data base 21 a for storing Web pages (information page data) as a plurality of pieces of guide information that are supplied to the respective Internet communication devices 14, 15, and a Web server engine 21 b (FIG. 2) which selects the Web pages in the Web page data base 21 a and supplies the resulting pages to the respective internet communication devices 14, 15 through the Internet 20, and also gives control instructions to the tele-con server 26 (FIG. 2).

[0043] The Web page data base 21 a stores a plurality of Web pages in the storing device 27 a, and outputs the Web page requested by the Web server engine 21 b to the corresponding Internet communication device 14, 15 through the Internet 20. The Web pages that are stored in the Web page data base 21 a are pages edited so as to include image information, if necessary, in addition to character information, that is, for example, viewing information pages that are associated with so-called I-mode (trade mark: NTT Mobile Communication Network (K.K.)), described in, for example, a description language referred to as compact HTML. More specifically, the Web page includes an ID input page that gives a message requesting an input of the ID number and password as character information, a device state display page that indicates the state of each electric apparatus 11 detected by the sensors and a control item page that is used for selecting an item on which each electric apparatus 11 is remote-controlled. The Web page data base 21 a is able to store the respective Web pages in the storing device 27 a in an updateable manner.

[0044] In this case, the control item page is set to display items of remote control in a manner so as to be selected in a simple display panel within the cellular phone 15 by clicking one of a plurality of listed-up control items or highlighting the display color of one of item characters to a complementary color while scrolling the screen. In particular, the control item pages are prepared in a divided manner into a plurality of individual pages having a hierarchical structure. For example, with respect to control item pages for an air conditioner serving as the electric apparatus 11, the control items that are selectable in the control item page on the upper-most hierarchy include “selection of cooling or heating mode”, “presence or absence of humidity setting”, “wind power”, “wind direction”, “timer setting” and the like, and each of the items is linked to a sub-page such as “specifying page for selection of cooling or heating mode”, “specifying page of presence or absence of humidity setting”, “specifying page for wind power”, “specifying page for wind direction” and “specifying page for timer setting”, which is located on the lower hierarchy; thus, it is possible to select a more specific selection item. Moreover, the Web page is designed so as to display the information of detection results of each electric apparatus 11 that are given through the tele-con server 26 in a partially combined manner.

[0045] Additionally, the above-mentioned compact HTML can be viewed by a cellular phone compatible with the I-mode (trade mark: NTT Mobile Communication Network (K.K.)), and can also be viewed by using a Web-page-viewing browser application that is introduced into the personal computer 14; thus, it is possible to view the pages by using a wide range of devices of various platforms.

[0046] The Web server engine 21 b of the Web serve 21 is a function element which is allowed to function through the operation of the CPU in accordance with the sequence defined by the predetermined program that has been preliminarily stored in the storing device 27 a, and, upon receipt of a request for connection from the cellular phone 15 or the personal computer 14 through the Internet 20, outputs the ID input page in the Web page data base 21 a through the Internet 20, and collates the ID number and the password inputted through the ID input page with a user managing table in the managing server 24 so as to identify the user. In the case when the identification of the user is negatively confirmed, a predetermined error message is outputted to the Internet communication devices 14, 15 as character information. In contrast, when the identification of the user is successfully confirmed, the device state display page is transmitted to the Internet communication devices 14, 15, and in response to a predetermined operation on the Internet communication device 14, 15, the corresponding control item page is transmitted to the Internet communication device 14, 15 to the Internet communication device 14, 15. When any one of the control items is further selected by the Internet communication device 14, 15, from the control item page thus transmitted, the selected control item is outputted to the tele-con server 26 as an instruction signal. Here, the software program that defines the functions of the Web server engine 21 b is stored in the storing device 27 a in an updateable manner.

[0047] The telephone automatic answering system 23, which is operated by the CPU (not shown) in accordance with a processing sequence described in the software program preliminarily stored in the predetermined storing device 27 b (FIG. 1), is provided with a communication function for communicating with each push-button-type telephone 13 through the public line network 22, and transmits a voice guidance to the corresponding Internet communication device 14, 15 as guide information through the public line network 22, and receives a dial-tone signal given from each Internet communication device 14, 15 in accordance with this voice guidance, and transmits an instruction signal for giving the corresponding instruction to the tele-con server 26 in accordance with the dial tone signal.

[0048] More specifically, the telephone automatic answering system 23 is provided with a dial tone input unit 23 a for receiving a dial tone signal transmitted from the push-button-type telephone 13 as the result of a push button operation, a message output unit 23 b which stores a plurality of predetermined messages, and transmits the corresponding message to the push-button-type telephone 13 as an analog-type voice guidance signal, and an automatic answering engine 23 c which gives an instruction for transmitting a voice guidance signal to the message output unit 23 b on the basis of the dial tone signal received by the dial tone input unit 23 a, and also controls the tele-con server 26.

[0049] The dial tone input unit 23 a converts the dial tone signal given from the push-button-type telephone 13 through the public line network 22 to predetermined coded data, and outputs the resulting data to the automatic answering engine 23 c.

[0050] The messages of the voice guidance, stored in the message output unit 23 b, include an ID input guide message for requesting inputs of the ID number and password to the user who is communicating through the push-button-type telephone 13, and a control item guide message which gives selection branches for controlling the electric apparatus 11 in accordance with a predetermined hierarchical structure in association with, for example, numbers in two digits. This control item guide message is composed of voice information that is preliminarily recorded by actual voice so as to guide the corresponding push-button operation through spoken language, and stored in the predetermined storing device 27 b with predetermined identification codes applied to its header portion. Moreover, the voice guidance is generated with one portion of the detection result information of each electric apparatus 11 given through the tele-con server 26 being combined therein.

[0051] Upon receipt of a request for a dial-up connection from a push-button-type telephone 13 through the public line network 22, the automatic answering engine 23 c gives an instruction to the message output unit 23 b so as to transmit the ID input guide message to the push-button-type telephone 13, and carries out the identification of the user by collating the ID number and password transmitted from the push-button telephone 13 in response to this message with the user managing table in the user managing server 24. Here, in the case when the identification of the user is negatively confirmed, a predetermined error message is outputted to the push-button-type telephone 13 as voice information.

[0052] Then, the automatic answering engine 23 c gives an instruction to the message output unit 23 b so as to transmit a control item guide message in accordance with the predetermined hierarchical structure. Moreover, when any selection is made through a push-button operation on the push-button-type telephone 13 in accordance with the control item guide message, the automatic answering engine 23 c gives an instruction to the message output unit 23 b so as to send a control item guide message on the basis of the dial tone signal given to the dial tone input unit 23 a, or further outputs an instruction signal to the tele-con server 26 so as to control the electric apparatus 11.

[0053] The user managing server 24, which, upon receipt of a request for connection from each of the Internet communication device 14, 15 and the push-button-type telephone 13 to the Web server 21 and the telephone automatic answering system 23, carries out the identifying process of each user who operates the Internet communication device 14, 15 or the push-button-type telephone 13 and makes the user associated with the corresponding electric apparatus 11, uses a computing system having a predetermined storing device 24 a such as a hard disk drive, CPU, RAM and the like, and particularly stores pieces of information, such as ID numbers and passwords used for identifying the respective users of the electric apparatuses 11, telephone numbers used for dial-up connecting to the respective electric apparatuses 11, IP (Internet Protocol) addresses that are used by the Web server 21 upon connection to the personal computer 14 or the cellular telephone 15 through the Internet 20 and other information related to the users (for example, addresses, names, sexes, etc.), as user managing table. Moreover, on the basis of the contents of remote control operations and the number of the remote control operations, a billing charge for each user is calculated, and stored in the user managing table. For example, a predetermined billing charge is imposed on each of the remote control operations, and different billing charges are determined in accordance with the contents of instructions of the remote control operations.

[0054] Additionally, the user managing table of the user managing server 24 is used as data base relating to the user identification in the Web server 21 and the telephone automatic answering system 23, and, in particular, upon receipt of a request for user identification from the Web server 21 and the telephone automatic answering system 23, the telephone number of the electric apparatus 11 that is associated with the corresponding user in the user managing table is transmitted to the tele-con server 26.

[0055] The tele-con server 26 is a function element which is allowed to function through the operation of the CPU in accordance with the software program that has been preliminarily stored in the storing device 27 c, and, after having been connected to the connection telephone number of the electric apparatus 11 supplied from the user managing server 24 through the packet network 25, generates a remote control signal preliminarily associated with the instruction signals given by the Web server 21 and the telephone automatic answering system 23, and transmits this remote control signal to the corresponding electric apparatuses 11 through the packet network 25.

[0056] Moreover, after temporarily storing the detection result information transmitted from each of the electric apparatuses 11 in the storing device 27 c, the tele-con server 26 outputs the information to the Web page data base 21 a as character data to be combined in one portion of the Web page stored in the Web page data base 21 a of the Web server 21, and also outputs voice data to the telephone automatic answering system 23 so as to be combined into one portion of the voice guidance recorded in the telephone automatic answering system 23.

[0057] Here, the software program which defines the functions of the tele-con server 26 is stored in the storing device 27 c in an updateable manner.

[0058] <Remote Control Processes by Push-Button Phone Operations>

[0059] Referring to a flow chart of FIG. 3, the following description will discuss remote control processes by push-button phone operations, which are carried out when the user is out in the remote control system of the electric apparatus 11 having the above-mentioned arrangement. In this case, it is supposed that the detection result information detected by the various sensors has been transmitted to the tele-con server 26 from the electric apparatus (air conditioner) 11, and stored therein.

[0060] First, as shown in step S01 in FIG. 3, when the user is out, he or she carries out a push-button operation on a push-button-type telephone 13 such as a public telephone so as to make a phone call to the telephone automatic answering system 23 of the base station 12.

[0061] The message output unit 23 b of the telephone automatic answering system 23 of the base station 12 gives a voice guidance at step S02 so as to urge the user to input the ID number (ID of the air conditioner) and the password.

[0062] In accordance with this voice guidance, after the user has inputted the ID number (ID of the air conditioner) and the password through the push-button operations of the push-button phone 13, dial tone signals corresponding to these push button operations are transmitted to the dial tone input unit 23 a of the telephone automatic answering system 23 through the public line network 22.

[0063] When the dial tone signals corresponding to the air conditioner ID and the password are given to the dial tone input unit 23 a of the telephone automatic answering system 23, the dial tone input unit 23 a converts the dial tone signals to the air conditioner ID and the password as the predetermined encoded data, and outputs the resulting data to the automatic answering engine 23 c. The automatic answering engine 23 c transmits the resulting air conditioner ID and the password to the user managing server 24.

[0064] At step S04, the user managing server 24 collates the air conditioner ID and the password given from the telephone automatic answering system 23 with the data base in the storing device 24 a so as to identify the user. Then, when it is determined at step S05 that the password is wrong, the processes from step S02 to step S04 are repeated. In contrast, when it is determined at step S05 that the password is correct, the sequence proceeds to step S06.

[0065] At step S06, the message, which corresponds to the detection result information stored in the tele-con server 26, for example, a message indicating that the room temperature is 30° C., is transmitted to the push-button-type telephone 13 through the public line network 22 from the message output unit 23 b as a voice guidance. Then, at step S07, the message output unit 23 b transmits a voice guidance to the push-button-type telephone 13 through the public line network 22 so as to urge the user to carry out the push-button operations relating to a state change in the air conditioner.

[0066] In accordance with this voice guidance, at step S08, the user carries out push-button operations corresponding to a change in the state of the air conditioner, for example, the start of a cooling operation, through the push-button-type telephone 13. The information relating to these push button operations are transmitted to the dial tone input unit 23 a of the telephone automatic answering system 23 as dial tone signals through the public line network 22. Upon receipt of the dial tone signals with respect to the control operation of the air conditioner, the dial tone input unit 23 a transmits these to the tele-con server 26 as encoded instruction signals. At this time, the telephone number of the electric apparatus 11 associated with the air conditioner ID is transmitted to the tele-con server 26 from the user managing server 24. On the basis of the telephone number given from the user managing server 24, the tele-con server 26 makes a connection to the communication circuit 11 d of the electric apparatus 11 through the packet network 25, and also transmits a remote control signal to the communication circuit lid of the telephone automatic answering system 23, on the basis of the instruction signal given from the telephone automatic answering system 23.

[0067] In accordance with the remote control signal given from the tele-con server 26 of the base station 12 through the packet network 25 and the communication circuit 11 d, the control system 11 b of the electric apparatus 11 carries out a driving operation of the driving system 11 a, for example, the start of a cooling operation.

[0068] Then, at step S09, a voice guidance is given so as to urge the user to carry out push button operations as to whether or not the push button operation at the push-button-type telephone 13 is terminated. In response to this guidance, when the user does not execute the corresponding push-button operation to terminate the push button operation, the sequence of operations of steps S06 to S08 is repeated. In contrast, when the user executes the corresponding push-button operation to terminate the push button operation, the operations are completed and the telephone connection is cut off.

[0069] <Remote Control Processes Through the Internet>

[0070] Referring to a flow chart of FIG. 4, the following description will discuss remote control processes through the Internet, which are carried out when the user is out in the remote control system of the electric apparatus 11 having the above-mentioned arrangement. In this case, it is supposed that the detection result information detected by the various sensors has been transmitted to the tele-con server 26 from the electric apparatus (air conditioner) 11, and stored therein.

[0071] First, as shown in step S11 in FIG. 4, when the user is out, he or she connects the Internet communication device 14, 15 to the Internet 20, and specifies the IP address of the base station 12 so as to access the Web server 21 through the Internet 20. In this case, he or she inputs the ID number (ID of air conditioner) and the password in predetermined input frames. These pieces of information are transmitted to the Web server 21 through the Internet 20.

[0072] When the information corresponding to the air conditioner ID and the password has been inputted to the Web server 21, the Web server engine 21 b transmits the air conditioner ID and the password to the user managing server 24.

[0073] At step S12, the user managing server 24 collates the air conditioner ID and the password given from the Web server 21 with the data base in the storing device 24 a so as to identify the user. When it is determined at step S13 that the password is wrong, the process of step S12 is repeated. In contrast, when it is determined at step S13 that the password is correct, the sequence proceeds to step S14.

[0074] At step S14, detection result information stored in the tele-con server 26, for example, information indicating the current temperature is combined into one portion of the Web page (apparatus state displaying page) in the Web page data base 21 a, and this is transmitted to the Internet communication device 14, 15 through the Internet 20. Moreover, at step S15, the Web server 21 transmits the Web page (control item page) in the Web page data base 21 a to the Internet communication device 14, 15 through the Internet 20.

[0075] The user selects a desired control item on the Internet communication device 14, 15 which the user is currently operating. For example, in the personal computer 14, the user selects a desired control item by clocking one of a plurality of control items, for example, the item of “start of a cooling operation”. Alternatively, in the cellular phone 15, the user selects a desired remote control item from a simple display panel within the cellular phone 15 by highlighting the display color of one of item characters to a complementary color while scrolling the screen.

[0076] Information concerning predetermined operations, such as the clicking operation and the scrolling operation, is transmitted to the Web server 21 through the Internet 20. Upon receipt of the information concerning to the control operations of the air conditioner, the Web server 21 transmits this information to the tele-con server 26 as instruction signals. At this time, the user managing server 24 transmits the telephone number of the electric apparatus 11 associated with the air conditioner ID to the tele-con server 26. On the basis of the telephone number given by the user managing server 24, the tele-con server 26 makes a connection to the communication circuit 11 d of the electric apparatus 11 through the packet network 25, and also transmits a remote control signal to the communication circuit 11 d of the Web server 21 on the basis of the instruction signal given by the Web server 21 (step S16).

[0077] In accordance with the remote control signal given from the tele-con server 26 of the base station 12 through the packet network 25 and the communication circuit 11 d, the control system 11 b of the electric apparatus II carries out a driving operation of the driving system 11 a.

[0078] Then, at step S17, when the user does not execute the corresponding operation to terminate the Internet communication device 14, 15, the operations of steps S14 to S16 are repeated. In contrast, when the user executes the corresponding operation to terminate the operations, the operations are completed and the telephone connection is cut off.

[0079] As described above, the remote control system of the electric apparatus 11 carries out remote control operations by using Internet communication device 14, 15 having a plurality of platforms, such as a personal computer 14 and a cellular phone 15, so as to drive-control the electric apparatus 11; thus, it becomes possible to provide a wider range of Internet communication devices 14, 15 so as to be readily selected by the user.

[0080] Moreover, the functions and information for remote control operations of the user are defined in association with updateable software programs and Web pages in the storing device 27 a, 27 b, 27 c, 24 a within the base station 12; thus, these software programs and Web pages can be updated by the storing device 27 a, 27 b, 27 c, 24 a in the base station 12 so that it becomes possible to easily add new function and remote control item easily. In comparison with the conventional system in which a tele-con is placed in the vicinity of the electric apparatus, it is possible to easily add a function with respect to the remote control.

[0081] Moreover, the tele-con server 26 and the electric apparatus II are connected to each other through the packet network 25 serving as a communication network so that, upon updating the software program for specifying the operations of the tele-con server 26, it is only necessary to carry out the maintenance process on the base station 12.

[0082] Furthermore, billing charges for remote control operations with respect to the users are stored in a user managing table so that it is possible to carry out a fair billing process easily.

[0083] In the present embodiment, in order to supply information from the base station 12 to the respective Internet communication devices 14, 15, compact HTML is adopted as the description language of this information, and Web pages described in this compact HTML are supplied to the respective Internet communication devices 14, 15; however, any description language may be used as long as it is compatible with a plurality of platforms. Alternatively, a description language that is applied to only one of the personal computer 14 and the cellular phone 15 may be used.

[0084] As described above, the remote control system of an electric apparatus is provided with a base station 12 which carries out a remote control operation on the electric apparatus 11 having a predetermined driving system 11 a through a predetermined communication network 25 and communication devices 13 to 15 which give instructions of the remote control operation of the above-mentioned driving system 11 a to the above-mentioned base station through predetermined communication paths 20, 22, and the above-mentioned base station carries out the above-mentioned remote control operation on the basis of an updateable software program installed therein and the above-mentioned instructions.
